I wanted to know why,is tyranitar used so freaking hard to take down even with 2x super effective hits!
Tell me the reason why it can't be countered easily from Grass, Water, Bug, Ground, Steel, and Fairy type attacks. The only real counter Tyranitar has is Fighting types, why?

tell some reasons why Tyranitar is hard to counter other than Tyranitar having high defensive stats.

There's two main reasons for this:

T-tar has excellent bulk, with 100/110/100 in HP, Defence and Special Defense respectively. That puts it among the bulkiest Pokemon out there, with only it's terrible typing preventing it from being a wall.

It's ability Sand Stream starts a Sandstorm, which boosts its special defense by a further 50%

Now this second point is critical. Most of the types that T-tar is weak to, have special moves. The exception? Fighting type moves, it's 4x weak to. That is the reason it's so hard to counter.

Further, items like Assault Vest which are very viable on it thanks it's tremendous movepool, only make it that much harder to counter.

I've played about 6 battles of RSE OU, so I can try to explain why Tyranitar used to be better. (it peaked in RSE and DPP and was still pretty good in BW, so this'll be mostly about RSE and DPP)
First, obviously, Landorus didn't exist back then.
Second, sand stream created an indefinitely long-lasting sandstorm. Players didn't have to worry about switching in on the sandstorm's 5th turn and losing it on the 6th. Like the Boxes person said, sandstorm raised Tyranitar's special defense in DPP.
Third, Tyranitar had two good attack stats and a lot of attacks, so it was able to hurt almost anything that tried to switch in. It had earthquake for Magneton, Metagross, Jirachi, and Heatran, fire blast and fire punch for Skarmory, Scizor, and Breloom, crunch and pursuit for Starmie and Gengar, and ice punch for Dragonite, Salamence, and Flygon. Hidden power's max power was 70 back then, so it was even able to nail Suicune and Swampert with grass hidden power. I didn't list rock slide or stone edge. Tyranitar was so good at using those two moves that Pokemon weak to them almost never became common threats.
Fourth, fighting attacks were bad. In RSE, close combat didn't exist, no fighting Pokemon could learn superpower, and high jump kick was almost as rare. Tyranitar was strong enough to survive the occasional brick break. DPP introduced close combat and made superpower more common, but there were still a lot of flying Pokemon and ghost Pokemon that were able to easily switch with Tyranitar when Tyranitar was threatened.
